Subject: [PATCH v5 11/20] drm/bridge: ti-sn65dsi86: Use pm_runtime autosuspend
Date: Fri, 23 Apr 2021 09:58:57 -0700 [thread overview]
Message-ID: <20210423095743.v5.11.I4c0b4a87e4dc19e5023b4d0a21bbfa6d9c09ebd8@changeid> (raw)
In-Reply-To: <20210423165906.2504169-1-dianders@chromium.org>
Let's make the bridge use autosuspend with a 500ms delay. This is in
preparation for promoting DP AUX transfers to their own sub-driver so
that we're not constantly powering up and down the device as we
transfer all the chunks.
